field-matrix-utils

Simple matrix library for Rust. Used for use with Finite fields.

Not safe for production use. It was only done for educational purposes.

Example

```rust // Arkworks has a macro to generate the modulus and generator for a finite field. // Type F is field element for use in our matrix. // You should be able to use any. This is just an example. use ark_ff::{Fp64, MontBackend};

[derive(ark_ff::MontConfig)]

[modulus = "127"]

[generator = "6"]

pub struct F127Config; type F = Fp64>;

// The good stuff starts here. let a: Matrix = Matrix::new(vec![ vec![F::from(1), F::from(2)], vec![F::from(3), F::from(4)], ]); let b: Matrix = a.transpose(); let c: Matrix = a + b; let d: Matrix = a * b; let det: F = a.determinant(); ... ```
